Java and JavaScript? Are they Similar?

Are there any similarities between Java and JavaScript?
Is JavaScript derived from Java or vice versa?

There are some of the common questions which we generally encounter from people who are not from the tech field or who are new to the programming world. And for sure, this may be due to the presence of the word "Java" in both of them. So lets see if there's really a similarity between the two or are they completely different from each other.

Introduction of java

Java the one of  the most commonly used and famous language these days was unveiled by James Gosling
dated back in 1991. It was then developed by team of Sun Microsystems named "Green Team" and it took close to 4 years to be available for public use. After saturating and capturing the whole market with the java run programs ,it is considered as one of the blessings to the programming world.

So what is the history behind JavaScript ?

So the nomenclature of  JavaScript was done dated back in 1990's .So, It was the time when the Internet was gaining popularity and Interned explorer and Netscape navigator were the most used browser at that time. Due to the increasing popularity the developers felt a need a develop some language that could act as mediocre between the user interactions and browser. One of the developer came up and developed a language and named it Live Script and integrated it into navigator.

This meant that the browser was literally interpreting the commands of the user; the code didn’t have to be compiled, and a plug-in was not required. Another programming language, Java, was gaining popularity around the same time, even though Java required a separate plug-in to function. Netscape saw the opportunity and renamed their language “JavaScript.” . I would say that this was indeed a very bad decision. 

Can you please explain the difference between the two?

Both Java and JavaScript are written, assembled and executed differently, and each has dramatic differences when it comes to what it is capable of doing.

Java has a wide range of use cases, ranging from modern Android Applications/ Desktop Applications to Complex web enterprise programming. By comparison, JavaScript has a use case mainly in web i.e. it is used to make the website more interactive. For example, When we need to add beautiful animations to the website we use JavaScript.

These are some on point and technical key differences

  • Java code must be compiled, and JavaScript code is all-text.
  • Each language requires different plug-ins.
  • JavaScript code is run on a browser only, while Java creates applications that run in a virtual machine or browser.
  • Java is an OOP (object-oriented programming) language, and JavaScript is specifically an OOP scripting language.


Java and JavaScript are definitely not similar to each other with both of them having different use cases. 
Taking of the web, JavaScript is the mostly popularly used language her whereas Java has it uses cases in places ranging from server side to client side applications.

While ending this article I would like to say that both Java and JavaScript are worth giving your precious time and learning them if you are entering the programming world. Also, Knowledge to these languages increases your chances of landing a job in the IT field more easily.
